An old friend from college found me via this blog. Hi Chuck! He and I used to work in the Autonomous Robot lab at Draper Laboratory. Here’s a paper about the robot I did my thesis on. I designed and implemented the mapping system. That robot was at least $50K. It was filled with lots of gadgets all sitting on top an (over)powered wheel chair. It made for impressive demos. However, the only thing non-military people wanted to know was when it would be able to do this, or wash windows.
